To the shaft E are secured the bevel-gears e" e", whose teeth mesh in the teeth of the corresponding bevel-gears ff, which latter are secured to the vertical shafts f f, journaled in bearings F F,as shown in Figs. 2 and 7. To the lower ends of the shafts ff are secured the spur-gears g g, the teeth of which mesh in the teeth of similar gears h h. (Shown in Figs. 2 and 7.) The gears h h are journaled at h and have pins or projections h h projecting upwardly through the blocks i 7l.

I I are transverse slots in the guide J, and the blocks i 1l are constrained to move in such slots, as shown in Fig. 7.

To the guide-piece J are secured by screws, as shown in Fig. 7, or made integral with the same the wire-feeders jj, through which the wire passes` after having been straightened, as shown in the section in Fig. 7.

j' is a spring-pressed pawl having teeth cut on its foot and which by the action of the spring j is normally held in contact with the wire, as shown, firmly gripping the wire during the forward or feeding stroke and slipping over the wire during the return stroke.

The guide-piece J is intermittently operated by any suitable or well-known mechanism.

To the plate K is secured or cast in one piece with the same the piece L, on which are pivoted at Z the toothed pawls Z Z", similar in form to the pawlsj and shown in detail in Fig.y 28. The object of these pawls is to prevent the wire from being drawn back during the return motion of the feeding device.

M M are standards attached to the frame of the machine, as shown, and which support the cross-bar M, on which are pivoted the drums or reels m m m m, on which the wire N is wound andwhich is carried from the said reels diagonally downward and under the guide-wheels annu, which guide-wheels have preferably V-shaped grooves on their periphery and are provided with guards n n u' 'n' to prevent the wire from jumping, as shownvin Figs. 2 and 7.

n" a5 are looscly-journaled rollers, in contact with which the wire is carried during the wire-straightening operation previous to being acted upon by the wire-feed device hereinabove described. y

d3 d8 are intermittently-operated gears cut on the faces of the disks D D, whose teeth engage the teeth of the pinionspp, said pinions being secured to shafts p' p', journaledin bearings attached to or made integral with the frame of the machine, as shown in Figs. 1 and 2. p p" are similar pinions secured to the opposite ends of the shafts p p', and one of said pinions is seen in Fig. 4 of the drawings, Where it will be noticed as meshing with the teeth of the pinions o" and 0B. The pinion o5 is made integral with the spur-gear 04, pivoted at 06 to the outwardly-projecting carriage-bed S9, as shown in Fig. 2.

o5 is a rack (shown in Figs. 1 and 3) in which the teeth of the spur-gear o4 mesh and which serves to move the carriage S and its box b inward to and outward from the center of the machine.

d4 d4 are the remaining sets of teeth cut on the faces of the disks D D, and they are shown in Figs. 1 and 2. These teeth are intermittent and mesh with the 'teeth of the pinions o o, which latter are made fast to the shafts o o', journaled in suitable bearings above the shafts 1J p', and the said shafts oo carry on their opposite ends the pinions o" o. (Shown in Figs. 1, 2, and 4.) The teeth of said pinions o" 0" mesh in the teeth of the pinions p" p before described and shown in Fig. 4. Y

q q q are slotted castings supporting the standards M M, and said slotted castings are preferably made integral with the legs A A and serve as guides and bearings for the blocks q q q (Shown in Figs. 3 and 5.) On the outer faces of said blocks are pivoted the rollers g3 g3 g4 g4, as shown in dotted lines in Figs. 3 and 5 and also in section in Fig. 2.

(Z5 d5 are cam-grooves formed on the interior IOO IIO

of the toothed disks D D, and said grooves neously, as follows: On the inside of each disk D is cast the inwardly-projecting lug d,

(shown in Figs. 3 and 5,) and said lug or ear or projection d6 is'made to form a continuation of the cam-surface CIT. (Shown in Fig. 5.) The lever-arms r 1"', which are integral with the shafts 'r r, are provided with rolls r3, and said rolls are operated upon by the projections d6 d6 during each revolution of the disk D and forced downwardly,traveling upon the cam-surface (ZT as the disk D is rot-ated in the direction shown by the arrow in Fig. 5. During this operation the clamping-cam r' is moved in the direction shown by the arrow thereon in Fig. 5, and at the time of this operation the lower edge of the carriage S has been driven inward to the center of the machine and, being located at the end ot' its stroke over the clamping-cams r r', is lifted bodily upward by said cams until the boxbody, supported on the movable carriage S, is in close clamped contact with the bottom portions of the staplers X Y. As the disks D D continue their rotary motion the stapler mechanism is brought into play, the rolls o'3fr3 meanwhile bearing upon the cam-surface (Z7, which latter is preferably made concentric with the disk D, and at the conclusion of the stapling operation the rolls are at the point d8, when they become released and the clamping-cams o" r 'fall back to their original positions. (Shown in Fig. 5.)

s represents the transverse box-support, secured to the carriage S or cast in one piece with the same, as may be desired, and said transverse support or brace is provided with a longitudinal slot s', adapted to receive the adjustable box-rests s" s, which latter have a number of pointed projections made on their upper faces, as shown in Figs. l, 2, and 1t, and which are forced into the box during the clamping operation, and thus additionally prevent any play of the box b' while it is being hinged.

s s3 are adjustable blocks provided with tempered spring stops, which latter bear against the ends of the box b', as shown, and are made flaring at their outer ends, thus serving as a ready means for centering the boxes on the carriage preparatory to hinging the same.

Below the transverse box-support s is a similar transverse adjustable cover-support t, also secured `to the carriage S, and said cover-support is provided with a projection t', preferably east in one piece with the transverse bar t, andwhich serves to support the bottom of the cover h2, as shown in Figs. l, 2, 3, and 4. Adjustable spring-stops t3 t, similar to the spring-stops s3 s3 before described, are arranged on the inner side of the transverse box-support s, as shown in Fig. l. The operator places the cover b2 between the said stops '/3 3 and allows its bottom to rest on the projection t, as shown. The inner side ot' the transverse bar s is beveled, as shown in Fig. 4, and against this beveled p0rtion the inner and upper portion of the boxcover b2 rests. Means for adjusting the position of the box and cover supports relative to the box-carriage are shown in Figs. l, 2, and 4, and consist of adjusting-screws s s, working loosely in the part S7 and through sliding wedges secured to the carriage-body. Such wedges, however, are not shown in the drawings, as any well-known means for adjustment may be used without departing from the essence oi' my invention. "When the adjustment, vertical or horizontal, or both, has been made, the clamping-bolt S8 is tightened, and thus the adjusting part S7 and carriage S are secured together.

U U and V V are adjustable rotary levers longitudinally adjustable upon the shaft E, and said levers are provided with rollers uit vu r, which rollers during the intermittent rotation of the shaft F. come in contact with the wire-cutting levers u u r 1f and cause said levers to be moved outwardly for a purpose hereinafter to be more fully described.

XV XV are clenching blocks adapted to cleuch the staples as they are driven through the box-cover h2, and said clenching-blocks are made longitudinally adjustable upon the work-support B and are secured in the desired position by tightening of the clampingbolts w fw.

fw is a projection on the clenching-block, which is used to bend the points of the staples into the cover h2, as shown in Fig. 3l. The clenehing of the staples for the box b' itself is done upon the box-rests s" s previously described, and said rests are provided with projections s4 s4, against which the points of the staples strike when driven and are then bent upwardly and into the box-body Z1', as shown in Fig. 3l.

Z Z are longitudinal driving-bars connected directly to lugs or ears .e e" on the interior of the guide-blocks q" q Q" q" by means of bolts e" 2", as shown in Fig. 5. These bars have a reciprocating radial movement the same as that of the blocks q q' q" q, and said bars are provided with the adjustable yokes .e3 .23 .e4 e4, which are clamped in their required positions upon the driving-bars by means of the binding-bolts .25, as shown in Figs. l, 2, and et. Said yokes are adapted to receive the trunnions or pins w13 at m18 .rw y y A1/1'7/,1/17 of the staple-driving mechanism, as will hereinafter be more fully described.

X X are the drivers for the box-cover staples, and Y Y are the drivers for the boxbody staples, and these two sets of drivers form one ot' the principal fea-tures of my invention.

Mechanism for simultaneously cutting and pointing the staple-wire, mechanism for forming the cnt and pointed wire into staples of a form as shown in Fig. 32, and mechanism for driving such Vt'ormed staples in interlockcd positions into the cover Wand body of the box b are contained in what I term the drivers, the description and operation of which will be treated separately.

X represents one ot the pair ot? drivers for IOO IIO

IZO

the box-cover staples, and 00' is the main casting of the same, preferably made in one piece with the plate K, on which the feeding device is secured, as shown in Fig. 6, said plate being adjustable on the work-supports B B and secured in its adj usted position by means of bolts 70 70' 70 70 passing through the slots 70" 70 70 70 in the plate K, as shown, and through the holes b b b b in the work-support, as represented, such adjustment being necessary in order to vary the distance between the hinged joints according to the size of the box to be hinged.

00 is a removable cap or cover piece made semicircular on its interior and, in connection with the corresponding semicircular channel in the part 00, is adapted to form the guide or bearing 0:2 for the driving device, which will hereinafter be described.

m3 is a spiral or inclined groove in the bottom of the bearing-surface 002, as shown in dotted lines in Figs. 8, 9; and 10 and in crosssection in Figs. 11,12, and 13. In said groove 003 is located a pin or pin and roll 001, adapted to be moved spirally in the slot, and said pinVV isV secured to the revoluble collar 006.

00'17 are extensions of the collar 006 and provided at their upper ends with the lips 008 w8.

The collar 006 is revolubly secured to the female portion of the driving device by means of a pin in the collar and which is received in an annular groove in the reduced part of the female portion, as shown in the drawings, or other suitable means may be employed for securing the collar and female portion 009 in their required relation without departing from the essence of my invention.

On the under side of the female portion of the staple-forming mechanism are made projections :010, rounded at their lower ends, as shown in Fig. 11, and in such projection 0010 is made a slotted recess 0011, adapted to receive the staple as it is formed.

0012 represents the male former, which is provided with a projecting pin 0013, and said male former is transversely movable relative to the path of the driver in the guide 0014, said guidebeing secured in a suitable manner to the base portion 00.

0015 is a slot in said guide, in which the male former 0012 is located.

0016 is a continuation of the slot 0015 and is made in the part 0;, as shown, and receives the lower part of the former 0:12 during the driving of the staples.

0017 m17 are fingers secured to the lower portion of the female portion of the forming device, as shown in Figs. 11, 12, 13,14, and 15, and said fingers are adapted to hold the male former 0012 up when the staple is being formed and to lower the same into its recess w16 just before the staple is driven.

x18 are trunnions made integral with the block 0019, and said trunnions are encompassed by the yokes e3 .z3 on the driving-bar Z before mentioned. The block 0019 is guided in the cut-away portions of the cover or cap 00 and base part as shown in Fig. 25, and said block is bored out cylindrically to receive the hammer-head 0020. The form of the block 0:19 is clearly shown in Fig. 26. The hammer-head 002 is screw-threaded on its upper end and maybe firmly held in its adjusted position by means of the locking-nut 0021. The lower part of said hammer-head terminates as a flange 0022 for a purpose as will be hereinafter more fullydescribed. The interior of the hammer; head is tapped to Areceive the upper screwthreaded portion of the hammer 0021, as shown in the drawings. In order to drive staples of varying lengths, it is evident that the position of the hammer in relation to the fixed male former 0012 must be changed, and this adjustment is accomplished as follows The hammer-head 0021 is held in a locked position relative to the block 0019 by means of the locking-nut 0021, and the hammer 0023 is also held fixed with respect to both the hammer-head 0020 and the block 0011 by means of the auxiliary nut 0024. It will be seen from the drawings that .when the nut 0021 is slackened the hammer-head 0020, which is internally screw-threaded, as before stated, and which is in reality an elongated nut, may be turned about the longitudinal axis of the hammer 0023 in either a right or left hand direction, and since the block 009, with its trunnions 0018 0018, is held fixed during such operation it is evident that the hammer 0023 will be moved in a longitudinal `direction either to or from the male former,

according to the manner of turning the head w20. After such adjustment has been accomplished both the nuts 0021 and 00211 are screwed down against their respective seats, and the head and hammer are thus held fixed in their adjusted positions. Said hammer is made shaped in section throughout its lower half, its extreme lower end terminating in an arc form t0 fit around the head of the formed staple, as shown.

0025 is a -l--shaped slot made in the cover or cap 00, the base 00, former-guide 0014, and eX- Vtending through the female portion of the forming device m9, as shown, said slot serving as a guide for the hammer and also in part as a guide for the formed staple as it is being driven. i During the downward movement of the staple forming device the collar 006 is caused to revolve on the reduced upper portion of the female former m9. This turning motion is caused by the travel of the roll 001 in its spiral recess x3, and the object of said partial rotation is to allow the female former 009 to move downward with the collar 006 and its extended portions'( 007during the irst'part of the stroke, thereby allowing the lips 00f1 008 l to escape from contact with the flange 0022 of the hammer-head 0020 slightly before the time of the staple-driving operation,during which operation the female forming device is stationary and the hammer m23 passed through it, as represented in Figs. 12'and 13.

The wire cutting and pointing mechanism for the box-cover staples is'shown in Figs. S,

.TOO

IIO

9, l0, 1i, 15, and 25, and consists of a lever n', to the lower end of which is secured the shaft u", suitably journaled in bearings, as shown. Said shaft carries at its opposite end the tooth n, which latter is received in a slot n, made in the lower cutter-block U5, as shown in Fig. 25, and through an aperture in said cutter-block n the staple-wire passes, as shown in Fig. S. n is the opposing cutterblock, and such block may be adjusted, if necessary, and held in its adjusted position by means of the set-screw nl. The cuttingsurfaces of each block are beveled at a suitable angle in order to form the requisite pointed ends to the staple-wire,

The operation of the cutting and forming mechanism for the boxecover staples is as follows: After the wire N has been fed through the cutter-block a5 by means of the feeding mechanism previously described and when such wire is in a position as shown in Fig. S the rollers n n on the rotary levers U Ucome in contact with the levers n u and force them outward, causing the cutter-block n to be moved in the direction of the arrow shown in Fig. 25 and the wire to be cut and pointed. The lever n is then returned to its original position by the influence of a suitable spring its. (Shown in Figs. 4 and 0.) lYhen the cutoff and pointed portion of wire has been 1ocated in a position as rshown in Fig. S, the driving-bar Z moves diagonally downward and causes the block Q01 to descend. The female portion of the forming device and the collar r6 and its projections m7 x7 descend with the block m19,- bnt the said collar and its projections are given a partial` rotary motion upon the reduced part of the female portion m9 due to the pin 004, which is constrained to move in the before-mentioned groove This spiral movement is continued until the extensions m7 a of the revoluble collar come opposite the cut-away portions of the block at, as represented in Fig. 9. During the downward movement of the collar at and its attached parts the cut and pointed portion of wire has been formed into a staple, as shown in Fig. 9, by means of the benders or projections m10 of the female portion7 which have bent the wire around the male former x12 (then in its upper position, as shown in Fig. 14) and received the formed staple in the slot or guide full. Upon the formation of the staple the male former is caused to descend into the groove m3, as shown in Figs. 12 and 15, by the action of the fingers :nw .juli upon the pins xls. At the close of the forming operation the hammer is located just above the formed staple, in a position as shown in Fig. 12, and as the block rc1 continues its downward motion the hammer forces the staple out of its guides, as shown in Figs. 10 and 13, and into the boxcover. After the staple has been driven into the box-cover b2 and clenched against the block 1V the drivin g-bar Z returns diagonally upward and causes the hammer, hammerhead, revoluble collar, rbc., to again return fil to their original positions, as shown in Fig. 8. No upward motion is imparted to the female portion no" nor to the revoluble collar until the flange m22 on the ham mer-head 052 comes in contact with the lips .128.118, causing the collar to be again partially revolved and to ascend with a spiral motion to its original position, the roller x4 meanwhile passing from the position shown by dotted lines in Fig. 10 to the position shown by dotted lines in Fig. S. As the revoluble collar x6 ascends the female portion 1r" follows it, though without a rotary motion, and during the upward movement of said female portion the wedge-shaped parts of the fin gers .1:17 .rw act upon the pin m13 of the male former m12 and force the said former upward into its original position. (Shown in Fig. S.)

Y represents one of the pair of drivers for the box-body staples, and f z/ is the main casting of the same, preferably made in one piece with the plate K, as shown in Fig. 6.

y' is a removable cap or cover-piece made semicircular on its interior and in connection with the corresponding hemispherical channel in the part y is adapted to form the guide or bearing yy2 for the forming device, which will hereinafter be described.

g3 is a spiral or inclined groove in the bottom of the bearing-surface y2, as shown in dotted lines in Figs. 1G, 17, and 18 and in cross'section in Figs. 19, 20, and 24. In said groove ya is located a pin or pin and roll p4, adapted to be moved diagonally in the groove, and said pin is secured to the female portion of the forming device if.

yl if are extensions of the female portion of the forming device {1/6, and said extensions are provided at their upper ends with the lips ggg/S. On the under side of the female portion of the staple-forming device 1/6 are made proj ections or benders 1/9, rounded at their lower ends, as shown in Fig. 20, and in such projections y is made a groove ym, adapted to receive the staple as it is formed.

The staples formed by the mechanismY Y are turned through an angle of ninety degrees while being formed and are driven interlocked with the staples previously driven into the box-cover by the mechanism X X, as shown in detail in Figs. 29, 80, and 31. The stapler Y differs from the stapler X in the following respects: The female former {1/6 and the male former y, with its guide U11, are designed to revolve in unison through an angle of ninety degrees, or thereabout, during the formation of the said staple in order that said staple may be located at its formation in a plane approximately at right angles to the plane of the staple formed by the X staples. To accomplish this, I dispense in the Y drivers with the revoluble collar @0G and stationary guide t shown in the X drivers, and in lieu thereof provide in the drivers Y Y means for rotating the staple forming parts through an angle of ninety degrees, as will be described hereinafter. The guide 'ti/ris made slotted,

as shown,to receive the male former yyl2,\vl1ich is transversely movable relative to the path of the driver, and said guide is revoluble in its bearings y2. y is an annular recess'cut around the lower'portion of said guide, and y is a pin secured in a suitable mannerto the base portion y and received in said annular recess {1]13, thus preventing any vertical movement of the guide 'Iz/11.

y p15 are lingers secured to the bottom part of the female portion of the forming device, as shown, and said fingers are adapted to force the male former p12 downward and outward after the staple has been formed and during the rotation of the forming device.

@/16 is a cam projection secured in a suitable manner to the base portion {L/ and shown in Figs. 16, 17, 1S, 22, and 23. The office of this cam is to force the male former upward and inward toits original position after the staple has been driven, and such work is performed during the return motion of the forming devlce.

yllfyl are trunnions made integral with the block p18, and said trunnions are encompassed by the yokes el .el on the driving-barZ before mentioned. The block y/ls is guided in the cut-away portions of the cover or cap y and base part y, as shown in Fig. 2l, and said block is bored out cylindrical to receive the hammer-head y19. The form of the block p18 is clearly shown in Fig. 27, where it will be noticed as being the duplicate of the block @019. (Shown in Fig. 26.) The hammer-head y19 is screw-threaded on its upper end and may be firmly held in its adjusted'position by means of the locking-nut rtf/20. The lower part of said hammer-head terminates as a flange gli for a purpose as will hereinafter lbe more fully described. The interior of the hammer-head is bored out cylindrical and tapped to receive the upper screw-threaded portion of the hammer @/22, as shown in the drawings. Said hammer is made -l--shaped in section throughout its lower half, and its extreme lower end terminates in an arc form to fit around the head. of the formed staple, as shown. y is a nut for securing thehammerg/22 to the hamm er-head y19 after the stroke of said hammer has been adjusted. The longitudinal adjustment of the hammer fylz with respect to the male former fy12 is obviously the same as that previously described for the hammer m23.

p24 is a -l- -shaped slot made in the cover or cap y', base portion y, revoluble former-guide y, and extending through the female portion of the forming device yl, as shown, said slot serving as a guide for the hammer and also in part as a guide for the formed staple as it is being driven.

The wire cutting and pointing mechanism for the box-body staples is shown in Figs. 16, 17, 18, and 24, and consists of a lever o', pivoted at o" in the slotted projection made on the cap y', one-half of said slotted projection being shown in Fig. 24. Said lever /U/ has a cam-shaped end o4, to which is pivoted at c5 the vertically-movable cylindrical cutter r6,

. preferably made slotted in its upper end to y receive the cam c4.

On the under side of the cylindrical cutter 'v6 is a projecting knife cl, adapted to be received in the slotted recess v8 of the opposing cutter-block r9, said cutterblock ci being shown in top plan view in Figs. 16, 17, and 1S and in longitudinal cross-section in Fig. '24. After the staple-Wire has been fed across the face of the cutter-block @9 by means of the feeding mechanism previously described the roller of the rotary lever c on the shaft V comes in contact with the lever c and forces it outward, causing the cutter-block vu to move downward and to cut out a short piece from the wire N, leaving the said wire in a condition as shown in Fig. 22. After the wire has thus been cut and pointed the lever v is returned to its original position by means of a suitable spring rl. (Shown in Figs. 4 and 6.)v l

Vhen the cut-off and pointed `portion of wire has been located in a position, as shown in Fig. 16, the driving-bar Z moves diagonally downward and `causes the block {1/1S to descend. The female portion of the forming device y descends with the said block, but with a rotary motion due to the pin and roll g4, which is constrained to Work in the spiral or inclined groove g3. The guide yu is caused to rotate in unison with the part ys, since the under portion of the part y is in contact with the upper surface of the guide y, as shown in Fig. 16. As the above-mentioned parts commence to rotate the benders or projections yl bend the cut-off portion of wire around the male portion of the forming device y into a staple and such staple is received in the slotted recess fylo. As soon as the staple has been formed the fingers y p15 act upon the pin in the said former 'y12 and force it downward and outward, as before described. At this stage of the operation the lips ys yl on the extensions yl yl come opposite the 'cut-awayportions of the block y, as shown in Fig. 17 and the pin and roll g4 has meanwhile traveled to the opposite end of its spiral or inclined groove ys. No further rotary motion is `imparted to the forming device, and the blockand hammer are now free to descend between said extensions yl yl to their lowest positions, as shown in Fig. 18, where the staple is shown Aas forced out of its guides at right angles to the staple previously driven into the box-cover by the mechanism X. After the staple has been driven into the box-body b and clenched against the block s the drivin g-bar Z returns diagonally upward and causes the hammer, hammer-head, forming device, dac., to return to their original positions, as shown in Fig. 16.

No upward motion is imparted to the female portion of the forming device y nor to the revoluble guide y until the flange yll comes in contact with the lips ys ys, causing TOO IIO

the part y and guideg/11 to return with an opposite spiral motion to their original positions.

During the upward movement of the abovementioned parts the fingers 1/15 'U15 are withdrawn from the pin of 'the male former p12 and said former is caused to move inward and upward, traveling on the cam-surface y1 to a position as shown in Fig. 92.

The consecutive operation of the entire hinging-machine is as follows: lVhen beltpower is applied to the driving-pulley c3, a continuous rotation is imparted to the d riving-shaft C and from it to the disks D D through the pinions c" c" and gears d CZ". During the rotation of said disks the intermittently-operated gears d3 cl3 intermesh with the pinions p p and cause the box carriage or table S (on which have been previously located by the operator the detached box b' and cover b9 in their relative positions, as shown in Fig. et) to move inward to the center of the machine. During the travel of the carriage or table inward the intermittently-operate d gears d d on the disks D D have intermeshed with the gears e c, secured to the shaft E, and said shaft E is caused to rotate. During the rotation of the shaft E the bevelgears e" e mesh in the bevel-gears f f,wl1ich causes the rotation of the vertical shafts f f and theirspur-gears g g. The rotation of said spur-gears g g causes the spur-gears h 7i, intermeshing with the former, to revolve, and the pins 7i 7L, secured to the gears 7L 7L, cause the blocks rz' to be moved transversely in their slots I I, thus imparting a forward horizontal motion to the guide-pieces .IJand the wire-feeders jj jj, secured to the said guides, thus feeding into the drivers X X Y Y the four ends of the staple-wires N, said wires N having been drawn through the straightening-rolls n n fn." a" 015 as 'a5 17,5. As the pins 7L 7L continue their course the guides J J and wire-feeders j j jj are returned to their original positions, while the toothed pawls Z Z Z' Z hold the wire already fed in xed position. At the completion of this wire straightening and feeding operation the rollers Iu fu, u yv on the respective rotary levers U U and V V act upon the respective cutting-levers n a' o @Zand in a manner previously described in detail cause the staple-wires N to be cut oilc at a proper length and pointed at these cut-off ends. It will be clearly seen from an inspection of the cutting mechanism that the cut-off ends of the continuous wires N are simultaneously pointed. At the completion of the above-mentioned operation the box and cover are located in their position for being hinged, and at such a time the projections d6 d6 of the cams (7F dl act upon the rollers T39-3 of the levers fr 9"', and thus the shafts r r, carrying at their inner ends the cams o" r', are partially rotated, causing the carriage S to be lifted slightly upward, thus securelyT clamping the box h against the bottom of the drivers X X Y Y, while the cover h2 is held fast between the clenching-blocks W W and the beveled support The rollers Q3 (13 on the blocks q' q are now moved downward in the cam-grooves d5d5, causing the drivingbar Z to descend diagonally downward toward the center ot' the machine, thereby operating the forming and driving mechanism for the box-cover staples in a manner as hereinbefore fully described. The staples for the box-cover b2 having been driven and clenched, the rollers Q* g4 on the blocks q q also move downward in the cam-grooves d5 d5, thus causing the driving-bar Z to descend diagonally downward toward the center of the machine, thereby operating the forming and driving mechanism for the box-body staples in a manner as hereinbefore fully described. The box 1J and its cover b2 now being securely and neatly hinged together by means of thcinterlocking and clenched wire staples the driving-bars Z Z ascend in order to their original up positions, the clampinglevers are released, and the box carriage or table is driven outward by means of the gears d" 0 o p 03 04 andrack o5 to its original position, when the operator removes the hinged box and replaces it with another box and detached cover to be hingedin a similar manner, and so on during the operation of the machine.
